While Samantha's age is left ambiguous throughout the series, it is heavily implied in several episodes that she is hundreds of years old. It is also established in the show that witches age very, very slowly. At this point in the series she makes reference to knowing two figures personally (William Shakespeare and Henry VIII) that establish the most accurate time frame for her age to this point in the series. As Henry VIII died in 1549 (and it is doubtful that Samantha would have known him as a young baby), then Samantha is at the very least 430 years old.

Samantha, Darrin, and the Tates supposedly live in Westport, CT, but the last scene with the gas station Samantha zapped up had mountains taller than any in the state of Connecticut.
